are commonly known in the trade as curtain stretchers.

The object of this invention is to obtain a curtain stretcher frame on which curtains can be readily secured, by means of pins which are or may be properly positioned to engage with a determined part or figure of said curtains. so that when said curtains are taken from the device a smooth appearance will be presented, particularly at the exposed, (or lower) end of said curtain. when the same is properly hung before a'window or other aperture, or thing.

An additional object is to obtain a device, of the kind described, which can be readily made rectangular in shape. and ot proper size, so that the curtain which has been stretched thereon, and dried, will present a regular and desired 21p iarance.

Additional objects are to obtain a device of the kind described which can be readily put into condition for use by persons not particularly skilled in mechanics; :1 device which is easily understood; which is economically made. not liable to break, and is durable.

In the drawings accompanying and forming a part hereof Figure l is a top plan view of a curtain stretcher frame embodying the invention, with a portion of a curtain in place thereon. Fig. 2- is a fragmentary end elevation of. said frame. Fig. 3 is a perspective of a metal corner which forms an ele ment of the curtain stretcher frame. Fig. 4: is a. perspective of an additional metal corner which also forms an element of the device. Fig. 5 is a perspective of a connector element of the device. 6 is an end elevation' of the connector element which is illustrated in detail in 5 and a side elevation of the head member attached thereto,

spective of one side of the head member of the device.

A reference character applied to desig nate a given part indicates said part throughout the several figures of the draw ing, wherever the samevappears.

A, A are the side rails of the frame, and B, B are the end rails. Side rails A, A are made in parts, or pieces (a, a which are joined together by connector C, when the device is set up for use, and which are separated when the device is to be stored, or shipped. Qonnector C is secured to part a of 'said rails by means of pins or rivets 'D, and when set up for use the part a. is secured in said connector by the pin (2. Connector C v is made of sheet metal bent up to obtain the body part 0 flanges 0 c and c on one edge of said body part, and flange c on the other edge oi said body part. Flanges c and c are in planes parallel to the side slot parts a, a of rails A, A the body part c in a plane parallel with theuiider side of said parts a, a and the flange 0 is in a plane parallel with the top or upper side of said parts a, a. Flange c extendsinto groove 11?, of parts (1-. a. The several flanges and the body part or connector C fits closely to the parts a, a of the rails A, A

E is a slidable connector which is provided with the body part and the several flanges of connector C, and said body part and flanges are'theretore lettered c c 0 c and 0'', '(see Fig. 6). Connectors E are secured in an adjusted position on the end.

rails B, 13 by pins F.

8-, G are which are adapted to s oport the side and end rails of the devi. and said legs are removably attached to ti s end rails B. B by means of the sheet met; head H; said head being secured to connec' tors E by means of pivot h. Sheet metal.

head H is designed to be. permanently at 1 endwise. Head H is made of duplicateparts" (see Fig. 9) which areattached or securedtogether by the rivets or bolts k i I, I and J, 5 are. corner pieces, which hdj'ustably connect the side rails A, A} theend rails B, B Corner pieces l, P, are

frights andlefts; as are also corner pieces J, .;';J and but one of said corner pieces are .illustratedin detail, in Figs. 3 and 4: Corer pieces'l, I (Fig-.4) permit the adjustment of the side rails relative to the end rail B; wh le'corner pieces J, J", permi the ad- 'justment of the side rails relative to the end date different Widths of curtains,'is' permitted by all the cornerpieces; while adjust-' ment of the end-rails to accommodate the lengthlof the. curtain must be done wholly by sliding corner pieces J, J, on. the side rails. 7 From this variation in the construction of the corner pieces :theend rail Bis in the same plane, as the side rails; while the end rail B isin a different plane from said side rails. .It therefore occurs that by attaching the end of the curtain which. is to be exposed to view, when the curta n is hung, to the end rail 13, that end of the curtain will be perfectly smooth; that is, in a determined plane; while the other end of said curtain' the' lower end as illustrated in Fig. 1 will have its corners and its end in a different plane. I I

End pieces I, I, are made of sheet metal which is bent up on two of its edges to obtain the same body part and flanges as con-- nectors C and E, and said body part and flanges are lettered the same as in said connectors, being a", c, c", c, and 0 respec-:

I *tively. End pieces J, J respectively, have additional bends to obtain the flange of, (Fig.

.3), and body part c.- Body part 0 mm a different plane from parallelithereto. v

K K, are groovesformed in the side walls of a groove which extends longitudinally in side rails A, A and end rails B, B and L, L, are metal plates in said grooves K. Plates L are thus-spaced from the bottom of the longitudinally extending grooves and are parallel to said bottom. Metal plates L are respectively provided with slots M, and N. P are bent pins which are located in slots M. PinsP are provided with heads p,

body part 0 but is "which are adapted to move in said longi.

tudinally extending grooves when parts p of said pins are in said slots M, and which are "not slidable in said longitudinally extending grooves when parts 79 of said pins are in slots N. The width of said longitudb 'iially eiftending ii'COVeS is sufficient to permit lateral mov ent of pins P when part 793 of said ins, are in grooves N By this construction the pins can be moved sufficiently to prmiflattachment of the curtains thereto at ,a proper, or suitable, place on side and end rails are slid in the corner pieces to obtain a suitable frame for the curtain which is to be placed thereon, and then the cotter pins F are forced into and through the holes f in said corner pieces and rails. The side rails are connected by connectors C, and secured by like cotter pins. The connectors E are moved on the end rails to'about midway of the frame, and then secured by like cotter pins. The edges of the curtain which is to be stretched are then brought into engagement with the pins P, and secured thereto. 1

In' using the device for small curtains parts a of the side rails may be used, omitting parts a, in which case the corner J, J areattached to said parts a.

I claim;

1. In a curtain stretcher frame, side and end rails, respectively provided with grooves on the upper faces thereof, in combination with corner pieces respectively made of sheet metal bent to obtain body parts in parallel planes, joined by a flangemtegral with an end of one "of said body parts, anda side of the other body part, said body parts lying on opposite sides of the connecting flange,

each of said body parts bent on one side rails; whereby said rails may be slid into ppsition in different planes in said corner pieces-and means to secure said rails in said position in the corner pieces.

2. In a'curtain stretcherframe, side and end rails in combination'with corner pieces, said rails respectively provided with longitudinally extending grooves on the? upper side thereof, metal plates in said grooves spaced from and parallel with the bottoms thereof, said plates provided with slots and with lateral slots communicating therewith, and pins in said rooves, said pins extending through said s ots, and provided with heads laterally and longitudinally movable in said grooves and said pins also adjustably movable in said first named slots to fit in a desired one of said lateral slots.
